A robot platform apparatus for high place work is provided to acquire grip force of wheels due to adhesive force of a platform without loss by contacting four wheels on all vertical walls according to the shape of a curve. A robot platform apparatus for high place work comprises a rotating link part(10) including pivot rotating axes(15,16), and front-wheel and rear-wheel rotating links(11,12); a wheel assembly part equipped with four wheels to be contacted with a vertical wall according to the shape of a curve; a compression spring restoring the front-wheel and the rear-wheel rotating links into the initial position; a strut bar(40) securing stiffness against lateral force acting on the wheels in steering a robot platform; a wheel cleaning device(50) removing foreign material of wheels in order to increase grip force of four wheels; a vacuum pad receiving vacuum pressure from a vacuum pump and providing adhesive force between a robot platform main body(1); a pneumatic cylinder controlling stroke according to the vacuum pressure within the vacuum pad; and a permanent magnet module whose height is adjusted by the pneumatic cylinder in order to prevent fall of a robot in case adhesive force is weak.
